22 Claims.

This invention relates to methods of, and machines for, roughing thesurfaces of soles which are to be cemented to shoes.

In the manufacture of cemented shoes, it is the general practice torough the overlasted margin of a shoe upper, and the marginal edge of anoutsole, for raising the leather fibres so that when the parts arecemented together, the fibres of both the upper and the outsole willintermingle and form a homogeneous bond of cement and fibre.

While roughing of uppers has been accomplished rapidly by using a Wideabrading wheel, roughing of outsoles has required much more time. In thepast, roughing an outsole has been accomplished by feeding one marginaledge of the sole past a roughing tool, turning the sole when the toeportion approaches the tool and then feeding the other marginal edgepast the too]. As the periphery of the average sole is over twentyinches, this progressively feeding of the sole past a single roughingtool was slow. If the feeding of the sole was accelerated in an effortto speed production, inferior roughing resulted and the life of theroughing tool was materially shortened.

This invention provides a machine which greatly shortens the soleroughing time by feed ing the sole straight through a pair of opposedrotary roughing tools mounted on swinging arms and having guide rollsthereon so that the tools will follow the contour of the soles androughs both sides of the attaching face of the sole at the same time.

A feature of the invention resides in the provision of mechanisms forautomatically feeding the soles to be roughed from a magazine wherebythe only responsibility of an operator is to keep the magazine loadedwith soles.

Another feature of the invention resides in having opposed roughingtools guided by the sole edges along the periphery of the sole.

Other features of the invention reside in the provisions of mechanismsfor automatically brushing the roughed soles to remove the loose fibresand for then discharging the soles from the machine.

An object of the invention is to reduce the time required for theroughing of outsoles.

Another object of the invention is the improvement of machines used forroughing outsoles.

A further object of the invention is the provision of an automaticallyoperated machine for roughing outsoles.

Other objects of the invention will in part be obvious and will in partappear hereinafter,

For a fuller understanding of the nature and objects of the inventionreference should be had to the following detailed description taken inconnection with the accompanying drawings, in which:

Fig. l is a plan view partially in section of a sole roughing machineembodying this invention, and illustrates a sole ready to be advancedfrom the bottom of a stack towards the roughing tools;

Fig. 2 isva sectional side elevation taken substantially along lines 2*2of Fig. 1;

' Fig. 3 is a partial plan view similar to Fig. l and illustratesadditionally a sole'being advanced between the roughing tools; I

Fig. 4 is a side elevation of the machine, part of the frame being insection;

Fig. 5 is a sectional plan view taken substantially along lines 55 ofFig. 4;

Fig. 6 is a sectional end elevation taken substantially along lines 6-6of Fig. 3; and

Fig. 7 is a fragmentary view on an enlarged scale illustrating aroughing tool applied to one edge of a sole, its associated guide rolland the underlying rubber covered sole supporting roll.

Referring to the drawings, the two roughing units It which may comprisea series of toothed Wheels Ii rotatably mounted on studs l2, are securedto the lower ends of vertical spindles [3 which are suitably journalledat their lower ends in bearings 14 and at their upper ends in thebearings l5 of a spindle housing IS. The spindles i3 are shouldered atI! and a thrust bearing l8 locates between the shoulder and the top ofthe bearing M which is threaded into the spindle housing It, thus theheight of the roughing tools Hi can be varied by adjusting the bearingI4 which may be locked in the desired position by means of the knurledlock nut l9.

To keep the roughing tools 10 in constant contact with the sole to beroughed, regardless of its variations in thickness above that for whichthe roughing tools have been set, and also to provide necessary pressureof the tools on the work the spindles iii are urged downwardly'bycompression springs 20 resting on the thrust bearings 2| located on thetop of the spindles, and the compression of the springs may be varied bysimply adjusting the plug 22 which is threaded into the upper end of thehousing l6.

As illustrated in Fig. 6 the upper ends of the spindles l3 terminate inthe form of elongate spur gears 23 which engage with drive gears 24attached to the lower ends of driving spindles 25, which are alsorotatable in the housing It,

and to the upper ends of which are attached the driven pulleys 26.

Projecting downwardly from the bosses of the spindle housings I6 are thestuds 3I to the lower ends of which are attached the free rolls or soleguides 32 which contact the edges of a sole as it advances under theroughing units I0, and which guide the roughing units to follow themarginal edges of the sole during the roughing operation.

The previously described roughing unit assemblies are supported by theswinging arms 33 which are rotatably supported about the ball bearings34, which are mounted on the stationary shafts 35, which may be cast asa part of the machine frame.

The shafts 35 are bored to receive the spindles 36 on the upper of whichare secured the pulleys 31 which rotate the pulleys 26 by the belts 38.Spur gears 39 are secured to the lower ends of the spindles 36 andintermesh whereby rotation of one of the spindles 36 effects rotation ofthe other. One of the spindles 36 is provided with a pulley 40 adjacentits upper end, this pulley is rotated from the shaft M by the belt 42which passes over the idler pulleys 43 and the pulley 44 secured to theshaft 4 I.

The shaft M is supported on bearings 45 at the rear of the frame of themachine and is keyed to a worm gear 46 of a speed reduction unit whichin turn is driven by the pulley 41 and belt 48 from a convenientlyplaced motor or line shaft.

The two swinging arms 33 which carry the roughing units I0, areidentical except that one is longer than the other as illustrated by thedrawings so that the roughing tools will overlap each other, therebyensuring full roughing at the toe of the sole. The arms 33 haveextensions 50 which are drilled to receive the light compression springs5| and the plunger rods 52. The plungers 53 are mounted on the innerends of the rods 52 and contact the lug 54 on the frame of the machine.The screws 55 in the outer ends of the arm extensions 50 serve to adjustthe tension of the springs 5i. The springs 5| act to urge the pivotedswinging arms 33 towards each other due to the plungers 53 contactingthe lug 54 and the screws 58 held in lugs 59 on the frame act as stopsto limit excessive outward movement of the arms 33. The table 60 whichforms the base of a magazine to hold the soles to be roughed, is boltedto the two side frame 6| of the machine. The soles are stacked by themachine operator as illustrated by Fig. 4, with their toe edges againstthe gate 62 which is movable vertically for permitting the bottom soleof the stack to pass therebeneath.

Fig. 4 illustrates a sole advancing under the gate. The sole pusher 63is guided in a slot 64 formed in the table 60 and is reciprocatedcontinuously through the link 65 which is pivoted at 66 to the pusher63, and through the connecting arm 61, by the eccentric 68 to which thearm 67 is attached at 69.

The eccentric 68 is mounted on and is driven directly by the shaft 10 onwhich is also mounted the gear II in mesh with the worm gear 46 on theshaft 41. The link 65 has a slot I2 in which the adjusting screw I3which is threaded into the connecting arm 61 passes, enabling adjustmentof the position of the pusher 63 to be made for accommodating solesextremely different in length.

Directly below the roughing units I0 is positioned a rubber covered solesupportingroll T5 keyed to the shaft I6 which is rotated by the gearfrom the front feed wheel shaft is pivoted to the machine frame at II8.

I! being in mesh with the gear 18 keyed to the shaft 10. The shaft I6rotates in a bracket which is pivotally supported on the shaft 19 and inthe stud 8| in alignment with the shaft I8 and secured to a lug 86depending from the underside of the table 60.

The bracket 80 is adjustable vertically by the nuts 82 of a stud 83which passes through a slot in an extension 84 of the bracket 80 and issecured at its upper end to a boss 85 on the table 60. The spring 81around the stud 83 and held in tension by the nuts 88 urges the roll I5upwardly towards the roughing units I0 until the extension 84 contactsthe adjusting nut 82 which also serves as a stop. Thus the driven solesupporting roll I5 is resiliently mounted for movement away from theroughing units I0.

On either side of the roll I5 there is an auxiliary sole supporting roll90 which is freely rotatable on the shafts 9| held in the backets 92pivoted at 93 to the machine frames. The left hand bracket 92 (facingFig. 4 of the drawings) has a downwardly extending tail 94 against whichone end of a compression spring 95 presses. The spring 95 is retained ina bore of the boss 96 attached to the table 60 and a threaded bushingI36 serves to tension the spring to urge the roll upward. The spring 91held in a boss 98 on the bracket 80 biases the plunger 99 upward intocontact with the bracket 92 of the right hand roll 90 and serves to urgethe roll upwards. Located directly above the rolls 90 are the toothedfeed wheels I00 which are keyed to the shafts I8I rotatable in thebearings I02 attached to the upper side of the table 60. The forwardfeed wheel, the right hand one facing Fig. 2 of the drawings is drivenby the gear I03 which is keyed to the shaft WI and which meshes with theidler gear I04 which in turnmeshes with the gear I8 on the shaft 10. Therear feed Wheel shaft is driven II by the sprocket wheels I06 and thechain I01.

To continue feeding of a sole past a dust removing brush I08 a rubbercovered delivery roll I09 is fixed on a shaft IIO journalled in bearingsThe delivery roll shaft II 0 is driven by the gear II2 which meshes withidler gears H3 and H4 which in turn mesh with a gear I I5 keyed to therear feed wheel shaft IOI. The rotary brush I08 is mounted above thedelivery roll I09 on a shaft II6 journalled in a bracket I I! which Thebrush is rotated against the direction of feed of the sole and serves toclean off the roughed surfaces of the soles as they appear thereunder,brushing the leather dust towards the nozzle I20 of a chamber I2I towhich a factory suction system may be connected.

Rotation of the brush I08 is accomplished by pulley I22 being belted tothe pulley I23 on the shaft M. In order to compensate for wear of thebrush I08 the bracket II I is adapted to be rotated around its pivotshaft II8 by set screws I24, held in lugs I25 on the machine frame,which contact the rear end of the bracket Ill and adjustment of the setscrews will elevate or lower the brush as desired.

To keep the soles from curling upward as they are fed from the stack andunder the front feed wheel I00 to the roughing units, a guide finger I26islocated in the center of the path of the soles ahead of the roughingunits I0. This finger I26 is attached to a vertically adjustable rodI2'I held in an extension arm I28 attached to the frame, and serves tokeep the soles flat as they are being operated upon. 7

The rods I30 comprise a magazine, the soles being stacked between therods I30, on the stacker table BI) as illustrated by Fig. 3. Through therods I30 being rotatably adjustable and through their being adjustabletowards and away from the space to be occupied by the soles, there canbe placed to contact at four points, stacked soles of a variety ofdifferent shapes and sizes. It is understood, of course, that all thesoles stacked each time should have substantially the same size andshape.

In operation, after the soles to be roughed are stacked between the rodsI30 on the table 60 and the gate 62 is adjusted to a heightcorresponding to the thickness of the soles to be roughed, the

motor which rotates the shaft 4| which drives all the driven mechanismin the machine is started.

The eccentric 68 then rotates and reciprocates the sole pusher 63causing it to push the lowermost sole in the stack under the gate 62 andthe forward toothed feed wheel I the teeth of which press against theupper surface of the sole as illustrated by Fig. 4. The feed wheel isrotated in a clockwise direction from the shaft 4| by the driveincluding the shaft I0, the shaft 89 and i the gears I03, I04 and 18described in the foregoing. As the sole progresses through the machineit passes under the rear feed wheel I09 which is rotated in a clockwisedirection by the sprocket wheels I06 and the chain it! described in theforegoing, and which feeds the sole at the rear portion of the machineand onto the rubber covered delivery roll I09. The roll I09 is rotatedas previously described and moves the sole from the machine against thebrush I68 causing it to -fall into the bin I35 as illustrated by Fig. 4.

The rubber covered rolls I and 90 which have been described in theforegoing, support the sole and aid in its movement through the machine.

The roughing units In are rotated in opposite directions by the drivesincluding the pulleys 31 and 26, the belts 38, and the gears describedin the foregoing. The guide rolls 32 which as has been described, rotatefreely in the shafts 3| contact the outer periphery of the sole as itprogresses through the machine, and are forced to follow the shape ofthesole and move the swinging arms 33 which support the roughing tools,towards and away from each other as required by the varying shape of thesole, whereby the roughing tools are caused to contact and rough themarginal edge of the sole.

Fig. 1 illustrates the guide rolls 32 as being in position forcontacting the toe portion of a sole. Fig. 3 illustrates the guide rolls32 as moved apart -by the passage of a sole therebetween and the toolsIE! having roughed the forward portion of the sole. Fig. 5 in the rearportion thereof, illustrates the rolls 32 guiding the roughing tools IE1above the heel edge of a sole.

The brush I08 is rotated in a counter-clockwise direction by the driveincluding the belt I29 and ing of soles and which through being entirelyautomatic, will not require skilled operators, and which thus willlessen the expense of operation. Since certain changes may be made in'the above construction and dilferent embodiments of the invention couldbe made without departing from the scope thereof, it is intended thatall matter contained in the above description or shown in theaccompanying drawings shall be interpreted as illustrative and not in alimiting sense.

It is also to be understood that the following claims are intended tocover all of the generic and specific features of the invention hereindescribed, and all statements of the scope of the invention which, as amatter of language, might be said to fall therebetween.
